How do i get to the water pump on a 2004 dodge stratus 2.7L?

Could be the idle air control, once these start hanging up inside, they can cause as variety of problems with idle speed (can become wildly random) or simply a failure to idle at all.

This could also be caused by a failing ignition pack.

The water pump is timing belt driven .so wil need to remove the engine mount,the timing belt cover and the crankshaft pulley (harmonic balancer). Then you will loosen the tensioner . Now u can remove the belt . Might need to remove the alternator and it's bracket so that the water pump will come out.

Fuel pump in the gas tank....relay under hood in junction box..

It is located on the fron of the motor. open the hood and look at the serpintine belt as it goes from pully to pully. youll have a water pump an a/c compressor, a power steering unit and the alternator the alternator will have a wire leading to the battery

thermostat housing was repalced on 2004 dodge stratus but is stil leaking from a hose. what could the problem be.

What size engine. You want to know how to remove the crankshaft pulley right?

Off the top of my head, having it done by a shop should run between $150-$300 bucks.

There are some vehicles that have unusual water pump designs that can cost 500-700 bucks to do, but I don't recall the Stratus being one.

Don

if you have dohc the 2.7 has 3 timing chains The primary chain goes around the crank sprocket the the water pump and around two intake cam sprockets. The other two chains run around seperate intake and exhaust cam sprockets, to synchronize the intake and exhaust valve timing.

If the water pump is inside the timing belt cover, you may as well replace the timing belt too since the labor is not cheap. You are looking at a few hundred bucks of labor, and add to that the parts which may cost around 150 bucks. So you are looking at around 500 bucks if you are lucky to find a shop that will do it at that price.
